Moreover, referring to FIGS. 3 to 7D collectively, the faucet structure 1 of the present invention is assembled in accordance with an assembling method described below, the assembling method including the steps as follows:
step one 41: providing the outer tube 11, on which the assembling gap 114 is provided; step two 42: combining the first half shell 14 into the outer tube 11, entering the first half shell 14 into the outer tube 11 through the hollow passage 112 formed by the outer tube 11 and placing the at least one supplying manifold passage 141 of the first half shell 14 in correspondence with the assembling gap 114; step three 43: combining the second half shell 15 into the outer tube 11, entering the second half shell 15 into the outer tube 11 in the assembling direction 5 and then moving it toward the first half shell 14, followed by sliding the second half shell 15 on the first assembling ramp 142 of the first half shell 14 via the second assembling ramp 151; step four 44: mounting the cap 13 to one of the end openings 113, at which the assembling direction 5 is directed, of the outer tube 11, while the sheltering portion 131 of the cap 13 closing the end opening 113, as well as placing the second threaded connection portion 132 of the cap 13 in correspondence with the first threaded connection portion 152 of the second half shell 15 and threadedly connecting the first threaded connection portion 152 with the second threaded connection portion 132, such that the second half shell 15 is moved toward the cap 13 for assembling, and the first assembling ramp 142 and the second assembling ramp 151 are abutted together during assembling process for pressing the first half shell 14 and the second half shell 15 against each other to complete the assembly.
Specifically, at the beginning of the assembly of the faucet structure 1 of the present invention, the outer tube 11 manufactured by machining and also formed with the assembling gap 114 is provided, followed by the step two 42. During the step two 42, entering the first half shell 14 into the hollow passage 112 from the two end openings 113 of the outer tube 11, and slipping it along the hollow passage 112, until the at least one supplying manifold passage 141 of the first half shell 14 is entrapped into the assembling gap 114 and the displacement of the first half shell 14 is restricted, so as to complete the step two 42. Subsequently, the step three 43 is performed to put the second half shell 15 into the outer tube 11. The second half shell 15 is required to enter into the hollow passage 112 through one of the end openings 113 which the first assembling ramp 142 faces, and the inclination of the second assembling ramp 151 is adjusted as required to be opposite to the inclination of the first assembling ramp 142 before entering the second half shell 15. Afterwards, the second half shell 15 is allowed to slide in the hollow passage 112, so as to enable the second half shell 15 to slide on the first assembling ramp 142 of the first half shell 14 via the second assembling ramp 151 thereof During this step, a moderate slippage with respect to the first half shell 14 is required for the second half shell 15, until the first threaded connection portion 152 and the second threaded connection portion 132 are threadedly connected when the cap 13 is combined, followed by entering the step four 44. The cap 13 is mounted to the end opening 113 which the first threaded connection portion 152 faces. At first, the sheltering portion 131 is provided in correspondence with the end opening 113, while the cap 13 is positioned such that the first threaded connection portion 152 is allowed to correspond to the second threaded connection portion 132, and the first threaded connection portion 152 is enabled to threadedly connect with the second threaded connection portion 132. Furthermore, during the threadedly connecting process, the second half shell 15 is displaced toward the cap 13 gradually under the effect of threaded connection. In the meantime, the second half shell 15 and the first half shell 14 are abutted against the tube wall 111, under the effect of the first assembling ramp 142 and the second assembling ramp 151, respectively. On the completion of threaded connection, furthermore, the first half shell 14 and the second half shell 15 are pressed against the tube wall 111 so as to complete the mounting of the flow guiding part 12.
In one embodiment of the present invention, the assembling gap 114 of the present invention is extendingly provided along the axis of the outer tube 11, as illustrated in FIG. 4. As such, each supplying manifold passage 141 of the flow guiding part 12 is also allowed to be extendingly provided along the axis of the outer tube 11 in the present invention. Thereby, it is only necessary for the user to incline hands moderately to carry the cleaning fluid provided by each supplying manifold passage 141, and the possibility of splashing the cleaning fluid on human clothing is reduced. For instance, when the hand-drying air is received by the faucet structure 1 from the blowing device, the hand-drying air is guided by each supplying manifold passage 141 and then spurted toward the human hands along the axis of the outer tube 11. Only moderate inclination of the human hands with respect to this axial direction is required to enable the water remained on the human hands to evaporate or drop under the effect of hand-drying air. Specifically, splashing water all around due to the hand-drying air is avoided. Further, the first half shell 14 of the present invention is provided with the mounting opening 143 openingly provided adjacent to the supplying manifold passage 141 and fitted therein with the sensing element 3. Furthermore, the mounting opening 143 is also provided in correspondence with the assembling gap 114, and located within the assembling gap 114 after the combination of the first half shell 14 is completed. Referring to FIG. 4 again, moreover, the first half shell 14 in one embodiment is provided with two supplying manifold passages 141. These supplying manifold passages 141 are extended along the axis of the outer tube 11 and located on the same extension line, respectively. In this embodiment, further, the mounting opening 143 may be provided between the two supplying manifold passages 141, such that the sensing element 3 is just located between the two supplying manifold passages 141 after the assembly is completed. In this way, when the human hands are detected by the sensing element 3 so as to supply the cleaning fluid via the two supplying manifold passages 141, the cleaning fluid may be applied to the human hands more completely.
Referring to FIGS. 7A to 8 together, in one embodiment, the faucet structure 1 further includes a flexible lining tube 16 fitted within the outer tube 11 as well as located between the tube wall 111 and the flow guiding part 12. The flexible lining tube 16 may be made of plastic materials having moderate flexibility. The clearance presented between the assembled tube wall 111 and the flow guiding part 12 may be eliminated to form air tightness by providing the flexible lining tube 16, in such a way the exudation of the cleaning fluid through this clearance may be avoided. Further, the flexible lining tube 16 is further provided with a fitting opening 161 located at the assembling gap 114 and shaped the same as the assembling gap 114 so as to allow the supplying manifold passage 141 to be placed therein. In this embodiment, moreover, the step two 42 of the assembling method of the present invention further includes a sub-step 421: combining the flexible lining tube 16 into the outer tube 11, in which the flexible lining tube 16 is entered through the hollow passage 112 formed by the outer tube 11, and the flexible lining tube 16 is positioned in correspondence with the assembling gap 114. Specifically, the flexible lining tube 16 is combined prior to the combination of the first half shell 14, such that the flexible lining tube 16 is sandwiched by the combined first half shell 14 and the outer tube 11 to achieve air tightness. In addition, during the second half shell 15 is combined, the second half shell 15 is further provided in a hollow region formed by the flexible lining tube 16, and then combined with the first half shell 14 within the flexible lining tube 16. On the completion of combining the first half shell 14 with the second half shell 15, the flexible lining tube 16 is also compressed, so as to reduce the clearance between components generated during the assembling process.
In one embodiment, referring to FIGS. 7A to 8 again, the cap 13 is provided with an accommodating portion 135 located in the sheltering portion 131 and depressed inwardly into the outer tube 11 so as to allow a light-emitting module 4 to be placed therein, and provided with a decorative panel 136 covering the sheltering portion 131 and being pervious to light generated by the light-emitting module 4. In this case, the accommodating portion 135 is sized and shaped in accordance with the structure of the light-emitting module 4 correspondingly. The light-emitting module 4 may be used as an indicator for the state of supply of the cleaning fluid to prompt the user through change in color or glittering brightness. Furthermore, the shape of the decorative panel 136 is adapted to the end opening 113. Besides, the decorative panel 136 is designed to possess a translucent region and a non-translucent region, such that light generated by the electrically-powered light-emitting module 4 may be emitted through the translucent region. In this embodiment, moreover, the step four 44 of the assembling method of the present invention further includes a sub-step 441: mounting the light-emitting module 4 and the decorative panel 136, in which the light-emitting module 4 is placed into the accommodating portion 135, and the decorative panel 136 is then placed in correspondence with the sheltering portion 131. Specifically, the light-emitting module 4 and the decorative panel 136 are assembled after threaded connection of the cap 13 with the second half shell 15 is completed. Initially, the light-emitting module 4 is mounted, in which the power required for the operation of the light-emitting module 4 is obtained from a control unit or a power unit via an electrical wire passing through the hollow passage 112, followed by combining the decorative panel 136. The decorative panel 136 may be combined onto the end opening 113 insertedly and allowed for closing the end opening 113 entirely after the assembly is completed.
The present invention has been detailed described above. However, the above description is only one preferred embodiment of the present invention, and should not be construed as limiting the scope of the present invention. All equivalent variations and modifications made in accordance with the patent claims should fall within the scope of the present invention.
